The trajectory of the mobile device is on a pathhaving network elements that provide varying transmission rates to themobile device.

The subject disclosure describes an illustrative example in which amobile device's trajectory is the cause of an anticipated networkvariability. It should be understood that the subject disclosure alsoapplies to other cases of anticipated network change such as a plannednetwork maintenance event, radio channel fading, or growing networkdemand based on network observations or historical periodic trends. Thesubject disclosure also applies to stationary devices in such cases.

FIG. 1 schematically illustrates an architecture 100 for a cellularnetwork. Mobile devices 110 with a variety of technologies (phones,tablets, etc.) have an end-to-end connection established with either aPublic Switched Telephone Network (PSTN) 160, in the case of voicetraffic, or an internet protocol network (Internet) 102, in the case ofdata traffic. As shown schematically in FIG. 1, a given mobile devicecan move through geographic regions having different and sometimesoverlapping networks with different characteristics. A mobile deviceaccesses a network by connecting with a base station 115 belonging tothat network. As shown in FIG. 1, the architecture can include a GlobalSystem for Mobile Communications (GSM) network 120, a 3G network 130,and/or a Long Term Evolution (LTE) network 140. In particular, LTEspecifications can define an internet protocol architecture with voiceover internet protocol (VoIP). FIG. 1 also illustrates a deviceaccessing the network through an Internet Service Provider (ISP)broadband connection 112.

In general, a mobile device that is in motion can connect with a varietyof networks and therefore receives and transmit data at different ratesat different times. A network itself (e.g. LTE network 140) may beintermittently available at a given location. It also will beappreciated that a mobile device client receiving data from a servermight not connect directly to that server, but rather to a proxy ornetwork of proxies that communicate and advantageously manage trafficover network segments with varying network characteristics.

FIG. 2 depicts an illustrative embodiment 200 in which a mobile device(in this example, personal media device 250) moving in and out ofmultiple network regions may encounter differing network capabilities. Aregion can correspond to an area of coverage of a distinct network or anarea of coverage of a segment of a larger network. Knowledge of anetwork region into which a personal media device may be moving allowsfor improvement of data transmission through the new region. In anembodiment, transmission of data packets (video, audio, etc. referred toherein generally as media segments) can be improved by leveragingnetwork knowledge (knowledge of real-time conditions in the networkregion) at the various locations that device 250 enters and traverses(e.g. as device 250 travels along path 210).

In the example shown in FIG. 2, the device 250 generally moves in region201, but moves into and out of area 202 where lower bandwidth isavailable, and traverses area 203 where higher bandwidth networking isavailable. Area 203 may correspond, for example, to a WiFi hotspot or alocation of LTE coverage.

In this embodiment, the mobile device 250 includes a processor on whichan MPEG DASH client 251 executes. The MPEG DASH client, running on themobile device, can take advantage of intermittent availability of higherbandwidth networks by means of a local buffer control algorithm 260 thatrequests a data packet having a bitrate based on the bandwidth at ananticipated location. In this embodiment, the anticipated location isbased on the trajectory of physical movement of the device. When ahigher bandwidth is predicted to be available, the buffer controlalgorithm can request additional low bitrate media segments, highbitrate segments, or a combination of the two to augment or replace thebuffering scheme used ordinarily (e.g. while moving in region 201). Thebuffer control algorithm can use network performance data 261 forvarious locations (including for example an anticipated location ofhotspot 203), and geographic information 262 pertaining to the locationof the device. The network performance data 261 can include networkcharacteristics such as jitter or loss rate, in addition to thebandwidth. In this embodiment, both the device location and the networkperformance can be dynamic; that is, the device 250 can be in motionalong path 210, while the higher bandwidth in hotspot 203 is availableonly intermittently.

In an embodiment, the client executing on the mobile device 250 can alsoevaluate network conditions for a plurality of available networks, todetermine an improved network connection for a mobile device at aparticular time. For example, as shown in FIG. 3, a mobile device at alocation 350 is able to connect with a Global System for MobileCommunications (GSM) network 320, a 3G network 330, or a Long TermEvolution (LTE) network 340. In this embodiment, the client device canprocess data regarding network traffic and network delays affecting theavailable bandwidth, and then dynamically select the network providingthe highest bandwidth actually available at that location.

It will be appreciated that transport characteristics of the network(traffic, delays, hotspots, etc.) may change over time, even for adevice that does not change its location. For example, the device 250can remain in region 203 while the high-bandwidth network in that regionis available only intermittently. In an embodiment, the networktransport characteristics include historical data regarding bandwidthavailable at a given location, so that availability of an intermittenthigh-bandwidth network (hotspot) can be predicted.

FIG. 4 illustrates a procedure 400 in which network information incombination with location awareness (knowledge of networkcharacteristics at a geographic location the client device is passingthrough) is used to select the most advantageous network for the clientdevice to connect with. In an embodiment, the client device requestsnetwork information comprising transport characteristics of the network(step 402) and obtains the network information from a server 401communicating with the client device (step 403). The network informationcan be provided by a server using a network map (step 404) withinformation on active traffic conditions, network delays, hotspotlocations, availability of intermittent connections, etc.

The client device is equipped with a positioning device 411 so that theclient device obtains geographic information (step 406). In thisembodiment, the client device has both positioning and motion sensing,so that the device's current location is known and movement to a newlocation can be predicted (step 408). The client device applies thedevice location and movement information (current and predictedlocations) to select the network with the highest locally availablebandwidth (step 410). The client device uses the network map informationto transition from one network to another to take advantage of thehighest available bandwidth (for example, moving from the networkcovering area 202 to the network providing hotspot 203). The clientdevice then obtains media segments (step 412) via the network having thebest performance at that time and at that location.

In another embodiment, the client device transmits its location andmovement data to server 401, which then determines the best-performingnetwork and automatically provides requested media segments using thatnetwork.

FIG. 5 is a flowchart showing a procedure 500 for requesting a mediasegment by a mobile device, in accordance with an embodiment. The mobiledevice's location and movement are tracked (step 502) to predict thedevice's location (step 504) over a certain time interval (for example,location in the next 10 seconds). Network information is provided by aserver using a network map with information on active trafficconditions, delays, etc. for the predicted location (step 506).

A request for a new media segment (e.g. video content) is scheduledusing network knowledge, particularly the network information regardingthe predicted location of the mobile device. When the mobile device isto make a request for a new media segment (step 508), it is determined(step 510) whether the mobile device is likely to enter a region ofhigher bandwidth coverage (e.g. WiFi hotspot 203) within the time periodfor predicting movement (e.g. within 5 seconds when location predictionis for 10 seconds). If not, the request is sent using the presentlyavailable bandwidth (step 518).

If higher bandwidth is predicted, the request for the new media segmentcan be deferred (step 512) and issued when the higher bandwidth coveragebecomes available (step 514). For example, if the mobile device bufferis running low such that it will be necessary to request a new mediasegment within a 5 to 10 second time interval, and it is determined thatthe mobile device is likely to enter a region of WiFi coverage within 5seconds, the request can be deferred and issued when the WiFi networkbecomes available. In addition, pending requests for media segments canbe canceled in anticipation of higher bandwidth (step 514) and thenre-issued (step 516) to take advantage of the locally greater bandwidth.In an embodiment, the mobile device can take advantage of the higherbandwidth by requesting additional media segments. Media segmentsreceived by the mobile device are stored in a buffer for futurepresentation (step 520). It will be appreciated that by schedulingrequests for additional media segments for a time when greater bandwidthis available, and buffering those additional media segments, degradationin viewing quality of media content can be avoided even if the mobiledevice subsequently operates in a region of reduced bandwidth.

In an embodiment, media requests are scheduled to be sent at a predictedtime of higher bandwidth availability. Scheduling can be dynamic, andcan be performed on a per client basis.

FIG. 6 depicts an illustrative embodiment of a first communicationsystem 600 for delivering media content. The communication system 600can represent an Internet Protocol Television (IPTV) media system.Communication system 600 can be overlaid or operably coupled with asystem supporting a mobile device client and providing media segments ata locally available bandwidth as another representative embodiment ofcommunication system 600.

As shown in FIG. 6, a mobile communication device 616, communicatingwith a base station 621 of network 617, can include a memory to storeinstructions and a controller coupled to the memory. The controller,responsive to executing the instructions, can perform operationsincluding requesting current transport characteristics of a networkcommunicatively coupled to a server and to the mobile device accordingto a trajectory of physical movement of the mobile device. Data packetscan be transported by the network to the mobile device according to adynamic adaptive streaming over hypertext transfer protocol. Thecontroller can also obtain the current transport characteristics of thenetwork and predict a future transport characteristic of the network inaccordance with the trajectory of the physical movement of the mobiledevice. The controller can also schedule a time for sending a request tothe server for transmission over the network of a data packet. The timefor sending the request for transmission of the data packet can bescheduled in accordance with the future transport characteristic and thecurrent transport characteristics of the network, to avoid a degradationin a viewing quality of video content presented by the mobile device.The operations further include sending the request responsive todetecting the time to send the request, receiving the data packetresponsive to sending the request, and buffering the data packet for afuture presentation of the media content, wherein the trajectory of thephysical movement of the mobile device is on a path having networkelements that provide varying transmission rates to the mobile device.

The IPTV media system can include a super head-end office (SHO) 610 withat least one super headend office server (SHS) 611 which receives mediacontent from satellite and/or terrestrial communication systems. Mediacontent can represent, for example, audio content, moving image contentsuch as 2D or 3D videos, video games, virtual reality content, stillimage content, and combinations thereof. The SHS server 611 can forwardpackets associated with the media content to one or more video head-endservers (VHS) 614 via a network of video head-end offices (VHO) 612according to a multicast communication protocol.

The VHS 614 can distribute multimedia broadcast content via an accessnetwork 618 to commercial and/or residential buildings 602 housing agateway 604 (such as a residential or commercial gateway). The accessnetwork 618 can represent a group of digital subscriber line accessmultiplexers (DSLAMs) located in a central office or a service areainterface that provide broadband services over fiber optical links orcopper twisted pairs 619 to buildings 602. The gateway 604 can usecommunication technology to distribute broadcast signals to mediaprocessors 606 such as Set-Top Boxes (STBs) which in turn presentbroadcast channels to media devices 608 such as computers or televisionsets managed in some instances by a media controller 607 (such as aninfrared or RF remote controller).

The gateway 604, the media processors 606, and media devices 608 canutilize tethered communication technologies (such as coaxial, powerlineor phone line wiring) or can operate over a wireless access protocolsuch as Wireless Fidelity (WiFi), Bluetooth®, Zigbee®, or other presentor next generation local or personal area wireless network technologies(Bluetooth® and ZigBee® are trademarks registered by the BluetoothSpecial Interest Group and the ZigBee Alliance, respectively). By way ofthese interfaces, unicast communications can also be invoked between themedia processors 606 and subsystems of the IPTV media system forservices such as video-on-demand (VoD), browsing an electronicprogramming guide (EPG), or other infrastructure services.

A satellite broadcast television system 629 can be used in the mediasystem of FIG. 6. The satellite broadcast television system can beoverlaid, operably coupled with, or replace the IPTV system as anotherrepresentative embodiment of communication system 600. In thisembodiment, signals transmitted by a satellite 615 that include mediacontent can be received by a satellite dish receiver 631 coupled to thebuilding 602. Modulated signals received by the satellite dish receiver631 can be transferred to the media processors 606 for demodulating,decoding, encoding, and/or distributing broadcast channels to the mediadevices 608. The media processors 606 can be equipped with a broadbandport to an Internet Service Provider (ISP) network 632 to enableinteractive services such as VoD and EPG as described above.

In yet another embodiment, an analog or digital cable broadcastdistribution system such as a cable TV system 633 can be overlaid,operably coupled with, or replace the IPTV system and/or the satelliteTV system as another representative embodiment of the communicationsystem 600. In this embodiment, the cable TV system 633 can provideInternet, telephony, and interactive media services.

The subject disclosure can apply to other present or next generationover-the-air and/or landline media content services system.

Some of the network elements of the IPTV media system can be coupled toone or more computing devices 630, a portion of which can operate as aweb server for providing web portal services over the ISP network 632 towireline media devices 608 or wireless communication devices 616.

Communication system 600 can also provide for all or a portion of thecomputing devices 630 to function as a network map server providingnetwork information as discussed above. The network map server can usecomputing and communication technology to provide information on networkperformance, which can include among other things, information onnetwork traffic and intermittent network availability. The mediaprocessors 606 and wireless communication devices 616 can be provisionedwith software functions to utilize the services of the network mapserver.

Multiple forms of media services can be offered to media devices overlandline technologies such as those described above. Additionally, mediaservices can be offered to media devices by way of a wireless accessbase station 617 operating according to common wireless access protocolssuch as Global System for Mobile or GSM, Code Division Multiple Accessor CDMA, Time Division Multiple Access or TDMA, Universal MobileTelecommunications or UMTS, World interoperability for Microwave orWiMAX, Software Defined Radio or SDR, Long Term Evolution or LTE, and soon. Other present and next generation wide area wireless access networktechnologies can be used in one or more embodiments of the subjectdisclosure.

FIG. 7 depicts an illustrative embodiment of a communication system 700employing an IP Multimedia Subsystem (IMS) network architecture tofacilitate the combined services of circuit-switched and packet-switchedsystems. Communication system 700 can be overlaid or operably coupledwith communication system 600 as another representative embodiment ofcommunication system 600. In particular, as shown in FIG. 7, a mobiledevice 722 can communicate with a base station of network 721 and obtainnetwork information regarding the performance of the network.

Communication system 700 can comprise a Home Subscriber Server (HSS)740, a management server 730, a tElephone NUmber Mapping (ENUM) server735, and other network elements of an IMS network 750. The IMS network750 can establish communications between IMS-compliant communicationdevices (CDs) 701, 702, Public Switched Telephone Network (PSTN) CDs703, 705, and combinations thereof by way of a Media Gateway ControlFunction (MGCF) 720 coupled to a PSTN network 760. The MGCF 720 need notbe used when a communication session involves IMS CD to IMS CDcommunications. A communication session involving at least one PSTN CDmay utilize the MGCF 720.

IMS CDs 701, 702 can register with the IMS network 750 by contacting aProxy Call Session Control Function (P-CSCF) which communicates with aninterrogating CSCF (I-CSCF), which in turn, communicates with a ServingCSCF (S-CSCF) to register the CDs with the HSS 740. To initiate acommunication session between CDs, an originating IMS CD 701 can submita Session Initiation Protocol (SIP INVITE) message to an originatingP-CSCF 704 which communicates with a corresponding originating S-CSCF706. The originating S-CSCF 706 can submit the SIP INVITE message to oneor more application servers (ASs) 717 that can provide a variety ofservices to IMS subscribers.

For example, the application servers 717 can be used to performoriginating call feature treatment functions on the calling party numberreceived by the originating S-CSCF 706 in the SIP INVITE message.Originating treatment functions can include determining whether thecalling party number has international calling services, call IDblocking, calling name blocking, 7-digit dialing, and/or is requestingspecial telephony features (e.g., *72 forward calls, *73 cancel callforwarding, *67 for caller ID blocking, and so on). Based on initialfilter criteria (iFCs) in a subscriber profile associated with a CD, oneor more application servers may be invoked to provide various calloriginating feature services.

Additionally, the originating S-CSCF 706 can submit queries to the ENUMsystem 735 to translate an E.164 telephone number in the SIP INVITEmessage to a SIP Uniform Resource Identifier (URI) if the terminatingcommunication device is IMS-compliant. The SIP URI can be used by anInterrogating CSCF (I-CSCF) 707 to submit a query to the HSS 740 toidentify a terminating S-CSCF 714 associated with a terminating IMS CDsuch as reference 702. Once identified, the I-CSCF 707 can submit theSIP INVITE message to the terminating S-CSCF 714. The terminating S-CSCF714 can then identify a terminating P-CSCF 716 associated with theterminating CD 702. The P-CSCF 716 may then signal the CD 702 toestablish Voice over Internet Protocol (VoIP) communication services,thereby enabling the calling and called parties to engage in voiceand/or data communications. Based on the iFCs in the subscriber profile,one or more application servers may be invoked to provide various callterminating feature services, such as call forwarding, do not disturb,music tones, simultaneous ringing, sequential ringing, etc.

In some instances the aforementioned communication process issymmetrical. Accordingly, the terms “originating” and “terminating” inFIG. 7 may be interchangeable. It is further noted that communicationsystem 700 can be adapted to support video conferencing. In addition,communication system 700 can be adapted to provide the IMS CDs 701, 702with the multimedia and Internet services of communication system 600 ofFIG. 6.

If the terminating communication device is instead a PSTN CD such as CD703 or CD 705 (in instances where the cellular phone only supportscircuit-switched voice communications), the ENUM system 735 can respondwith an unsuccessful address resolution which can cause the originatingS-CSCF 706 to forward the call to the MGCF 720 via a Breakout GatewayControl Function (BGCF) 719. The MGCF 720 can then initiate the call tothe terminating PSTN CD over the PSTN network 760 to enable the callingand called parties to engage in voice and/or data communications.

It is further appreciated that the CDs of FIG. 7 can operate as wirelineor wireless devices. For example, the CDs of FIG. 7 can becommunicatively coupled to a cellular base station 721, a femtocell, aWiFi router, a Digital Enhanced Cordless Telecommunications (DECT) baseunit, or another suitable wireless access unit to establishcommunications with the IMS network 750 of FIG. 7. The cellular accessbase station 721 can operate according to common wireless accessprotocols such as GSM, CDMA, TDMA, UMTS, WiMax, SDR, LTE, and so on.Other present and next generation wireless network technologies can beused by one or more embodiments of the subject disclosure. Accordingly,multiple wireline and wireless communication technologies can be used bythe CDs of FIG. 7.

Cellular phones supporting LTE can support packet-switched voice andpacket-switched data communications and thus may operate asIMS-compliant mobile devices 722. In this embodiment, the cellular basestation 721 may communicate directly with the IMS network 750 as shownby the arrow connecting the cellular base station 721 and the P-CSCF716. In particular, the cellular phone (mobile device) comprises aprocessor and can perform a method including requesting, by the mobiledevice, current transport characteristics of a network communicativelycoupled to a server and to the mobile device according to a trajectoryof the mobile device. Data packets are transported by the network to themobile device according to a dynamic adaptive streaming over hypertexttransfer protocol. The method can include obtaining, by the mobiledevice, the current transport characteristics of the network. The methodcan include predicting, by the mobile device, a future transportcharacteristic of the network in accordance with the trajectory of themobile device. The method can include scheduling, by the mobile device,a time for sending a request to the server for transmission over thenetwork of a data packet. The time for sending the request fortransmission of the data packet can be scheduled in accordance with thefuture transport characteristic and the current transportcharacteristics of the network, to avoid a degradation in a viewingquality of media content presented by the mobile device. The trajectoryof the mobile device is on a path having network elements that providevarying transmission rates to the mobile device.

Alternative forms of a CSCF can operate in a device, system, component,or other form of centralized or distributed hardware and/or software.Indeed, a respective CSCF may be embodied as a respective CSCF systemhaving one or more computers or servers, either centralized ordistributed, where each computer or server may be configured to performor provide, in whole or in part, any method, step, or functionalitydescribed herein in accordance with a respective CSCF. Likewise, otherfunctions, servers and computers described herein, including but notlimited to, the HSS, the ENUM server, the BGCF, and the MGCF, can beembodied in a respective system having one or more computers or servers,either centralized or distributed, where each computer or server may beconfigured to perform or provide, in whole or in part, any method, step,or functionality described herein in accordance with a respectivefunction, server, or computer.

The network map server of FIG. 6 can be operably coupled to the secondcommunication system 700 for purposes similar to those described above.The network map server can be an integral part of the applicationserver(s) 717, which can be adapted to the operations of the IMS network750.

For illustration purposes only, the terms S-CSCF, P-CSCF, I-CSCF, and soon, can be server devices, but may be referred to in the subjectdisclosure without the word “server.” It is also understood that anyform of a CSCF server can operate in a device, system, component, orother form of centralized or distributed hardware and software. It isfurther noted that these terms and other terms such as DIAMETER commandsare terms can include features, methodologies, and/or fields that may bedescribed in whole or in part by standards bodies such as 3^(rd)Generation Partnership Project (3GPP). It is further noted that some orall embodiments of the subject disclosure may in whole or in partmodify, supplement, or otherwise supersede final or proposed standardspublished and promulgated by 3GPP.
